Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] The embodiment of the present invention provides a high-speed serial communication method suitable for low-cost sub-nodes. The method is as follows: the communication modulation method is voltage modulation, and a modulation disturbance is superimposed on the power supply cable, indicating data '0', without modulation disturbance When , it means data '1'. It can also be defined as superimposing a modulation disturbance on the power supply cable, which means data '1'. When there is no modulation disturbance, it means data '0';

[0017] The modulation disturbance consists of two continuous flu...

Abstract

The invention discloses a high-speed serial communication method applicable to a low-cost child node. The method comprises steps as follows: a modulation mode of communication adopts voltage modulation, a modulation disturbance is superimposed on a power supply cable and is denoted with data '0', and no modulation disturbance is denoted with data '1', or a modulation disturbance is superimposed on the power supply cable and is denoted with data '1', and no modulation disturbance is denoted with data '0'; the modulation disturbance comprises two continuous fluctuations, and the two fluctuations have basically identical fluctuation shapes, but have opposite polarities; the initial phases of the modulation disturbance sent by a host and the modulation disturbance sent by a submachine are opposite. On the premise of no adding of any coding and decoding complexity, consumption of devices on a bus because of irrelevant data processing is avoided, and the system cost is substantially reduced.

Description

Technical field: [0001] The invention relates to the technical field of communication methods, in particular to a high-speed serial communication method suitable for low-cost sub-nodes. Background technique: [0002] In fieldbus communication, the master-slave structure is a widely used communication topology. In this structure, a host and multiple slaves are included. In most cases, the host is the initiator and controller of the communication, and the host communicates with each slave separately through a certain slave identification mechanism. [0003] The most commonly used identification mechanism is the bus address mechanism. Each sub-machine and the host have a unique communication address in the system. When the host communicates with a certain sub-machine, the bus address of the sub-machine is placed before the data / command to be sent, and they are sent together, which is called a frame; The child node monitors the bus data at the same time. After receiving the f...
